About the Role

As a Senior Software Engineer on the Pulse Team, you will design, develop, and maintain high-performance software solutions at the core of our quantum computing technology. You will act as a technical leader, driving architectural decisions, championing best practices, and mentoring junior engineers. Your work will involve developing the low-level software stack, closely integrated with hardware, bridging scientific R&D, data engineering, and platform design to enable rapid iteration for researchers and physicists.

Responsibilities

  • Design and maintain low-level drivers and hardware abstraction layers for control electronics, including signal generators, AWGs, digitizers, and custom FPGA-based instruments.
  • Define clean hardware/software interfaces that decouple control electronics from higher-level experiment logic, enabling fast hardware iteration without breaking the software stack.
  • Collaborate closely with physicists and researchers to ensure models and interfaces reflect real experimental needs and enable fast iteration.
  • Drive long-term architectural strategy, technical roadmap, and cross-organizational alignment.
  • Mentor teams, challenge assumptions, and lead architecture reviews across the platform department.

Requirements

  • 8+ years of experience designing low-level software stacks close to the hardware.
  • Superior engineering proficiency in Python.
  • Ability to define clean abstractions and synchronization mechanisms for hardware/software interaction loops, including real-time constraints, timing accuracy, and low-latency communication with control hardware.
  • Hands-on experience writing drivers or low-level interfaces for hardware instruments (e.g., via VISA, SCPI, PCIe, Ethernet/UDP, or custom protocols).
  • Solid understanding of Digital Signal Processing (DSP) fundamentals—sampling, filtering, modulation/demodulation, and their application to waveform generation and acquisition.
  • Ability to collaborate and challenge ideas with physicists, academic-level experts, and deeply technical researchers.
  • Strong technical leadership: able to influence direction, align teams, and support cross-domain decision-making.
  • Hands-on experience with automation systems (schedulers, workflow engines, configuration graphs, data pipelines).
  • Strong product mindset: ability to think about end-to-end delivery, user experience, reliability, and long-term lifecycle.
  • Experience delivering a hardware-backed product (accelerators, HPC nodes, scientific instruments) to external users.
